ROMERO-ARIAS, José Roberto et al. Inflorescence cell differentiation model of Arabidopsis thaliana. TIP [online]. 2010, vol.13, n.2, pp.91-102. ISSN 1405-888X.

We address the cell differentiation problem assuming that cells receive space-time information from the environment that allows them to change their gene expression through the interaction between macroscopic physical fields and their genetic networks. The fundamental idea is that every cell's genetic network responds to the dynamical evolution of the macroscopic fields that break the space-time symmetry and provide information for selective gene expression. Hence, we use a coevolution model between two physical systems reacting chemically in order to describe the inflorescence of Arabidopsis thaliana since this plant has been one of the most studied organisms and there is an enormous quantity of experimental data about the time evolution of its organs and also about the gene activity responsible for those changes.

Keywords : Models of inflorescence; morphogenesis; genetic networks.
